In some MacBook Air and presumably many other MacBooks the trackpad tend to become loose or rattle after a couple of years. It is a often read mistake, that this can be adjusted or "repaired" by the central adjustment screw of the trackpad (marked in step 10). This will only make it worse as the reason for the loose trackpad however can be found in the failure of two tiny buffers, that work as upper stop of the trackpad. Tiny as they are, few seem to know them and unsurprisingly they fail after countless workcycles. I did not find them as spare part but please leave a comment, in case they are avialable. I will then update this guide.

In rest position, they press the trackpad against the contact point of the mentioned adjustment screw and the click button. When you click, they decompress and when you release, they are recompressed by the bounce of the click button, which explains why their elastic force must be rather small.

Steps 1-11 base on older guides, which contain some wrong information: Do not follow step 10! The mentioned screw is only for adjustment of the clickpoint and must not be unscrewed. The trackpad already comes out after Step 8

In this working position, we act directly above the display. So better place a thick cloth or any other protective material between screen an lower case before you begin.

When handling the battery, avoid squeezing or touching the four exposed lithium polymer cells.

Lift the battery from its edge nearest the logic board and remove it from the upper case.

When installing the new battery, if there is a thin plastic film on your replacement battery, do not attempt to remove it. It is glued on and protects the battery pack while it is inside the MacBook.

If you're installing a new battery, you should calibrate it after installation:

Charge it to 100%, and then keep charging it for at least 2 more hours. Then, unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.

If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook's SMC.

Hello, good tutorial. Today on my Macbook Air disarm the trackpad, since it was loose and it sounded when using it. The only solution and that was good for me, was to tighten the central screw, to the point that it remained firm and allowed the clicks.
